Abstract
The utility model discloses a kind of for the sander of road bed board and pedestal board concrete faulting of slab ends in ballastless track bed plate plate expansion joint, it is made of angle grinder, angle grinding and three parts of square type pipe, angle grinder（2）Mounted on rectangular tube（3）End, angle grinding（6）Mounted on the other end, angle grinder（2）It is ground with angle（6）Between pass through belt（5）Transmission.The utility model is capable of the face length of angle of strike grinding, it is polished to the concrete faulting of slab ends problem of road bed board expansion joint both ends inner wall road bed board and base board, so as to solve the problems, such as that operation side is restricted, polishing task is completed, reaches the shape appearance of construction technical requirement.
Description
Technical field
The utility model is related to a kind of road bed board expansion joint sanders.
Background technology
It is true first in installation form because road bed board is separately constructed with base board in ballastless track of high-speed railway construction
Mouth and base board side are closely connected under guarantor's template, and strut firm supporting is right on the basis of plate physical dimension meets code requirement
Vertical framework carries out band filling and adjusts, and ensures template line style and verticality.Plate stitch template need to strictly control width dimensions, and use card
Tool is fixed.If fixation is insecure, road bed board and base board can generate faulting of slab ends after concrete construction, influence outside road bed board shape
It sees, it is therefore desirable to which the concrete faulting of slab ends of road bed board and base board to road bed board expansion joint both ends inner wall is polished.But due to
Operation faciostenosis at road bed board expansion joint, expansion joint spacing width extremely inconvenient to the operation of internal-wall concrete faulting of slab ends polishing operation
Only 100mm, depth but have 500mm, are limited by work surface, and general tool can not polish.
The content of the invention
The technical issues of the utility model solves:, provide it is a kind of can put between ballastless track bed board expansion joint, carry out
The milling tools of road bed board and base board faulting of slab ends, to solve the problems, such as that polishing caused by polishing operation faciostenosis is difficult.
Technical solution：
A kind of ballastless track bed board expansion joint sander, including angle grinder, angle grinder is mounted on rectangle tube end, angle mill
Piece is mounted on the other end, is connected between angle grinder and angle grinding by belt.
Angle grinder is fixed on rectangle tube opening right end top by fixing card, and angle grinding is fixed on rectangular tube by mounting base
Left end lower part, belt pass through among rectangular tube, and connection angle grinder=drive angle grinding rotates.
Bearing is installed, the shaft of mounting base is mounted on bearings, and skin is equipped on bearing in the tube wall of rectangular tube left end
Pin is worn in belt wheel, shaft connection, is worn pin and is stretched out tube wall for established angle grinding.
Mounting base is made of linkage section, bearing section and segregation section, and linkage section is used for and rectangular tube cooperation, bearing section and separation
Respectively there are half bearing groove and shaft hole in section, complete bearing groove and shaft hole are formed after bearing section and segregation section split.
Bearing section and segregation section are bolted, the threaded hole cooperation after bolt-through segregation section and on bearing section.
The beneficial effects of the utility model：
1st, the present apparatus be capable of angle of strike grinding face length, be polished to road bed board expansion joint both ends inner wall road bed board and
The concrete faulting of slab ends of base board, so as to solve the problems, such as that operation side is restricted.Expansion joint sander can deeply handle into
Stenostomia and the deeper concrete faulting of slab ends face of depth, do not influence to complete construction task in the case of concrete structure.
2nd, according to the needs of polishing corresponding grinding disc can be selected to mill, the angle of inclination of grinding and workpiece is about during corase grinding
It is advisable in 30 to 40 degree, firmly uniformly achievees the effect that be polished flat suitable.
3rd, the length of square type pipe can be lengthened or shortened according to construction site situation, to meet the needs of site operation.
4th, specially designed installation holder structure, easy to process and assembling.
Description of the drawings：
Fig. 1 is the utility model overall structure diagram one.
Fig. 2 is the utility model mounting base structure diagram.
Fig. 3 is mounting base top plan view.
Fig. 4 is mounting base side cutaway view.
Specific embodiment：
The utility model patent embodiment：A kind of ballastless track bed board expansion joint sander is ground including angle grinder 2, angle
Piece 6 and rectangular tube 3 form.Angle grinder 2 is fixed on the opening right end of rectangular tube 3 top by fixing card 1, and angle grinding passes through mounting base
4 are fixed on 3 left end lower part of rectangular tube,
Mounting base 4 is made of linkage section 41, bearing section 42 and segregation section 43, and linkage section 41 is used for and rectangular tube 3 coordinates, can
To be inserted into 3 lower end of rectangular tube, there is bolt hole 45 on rectangular tube 3 and linkage section 41, linkage section 41 is fixed on by rectangle by bolt
3 lower end of pipe.41 left side of linkage section connects bearing section 42, respectively has half bearing groove 46 and shaft on bearing section 42 and segregation section 43
Hole, such as Fig. 2 are installed belt pulley 7 on bearing 8, bearing 8 are installed in the bearing groove 43 of bearing section 42, then by bearing section
42 and 43 split of segregation section, there are bolt mounting holes on four angles of segregation section 43, bolt 44 runs through after segregation section 43 and bearing section
Threaded hole on 42, which is combined together, fixes bearing section 42 and segregation section 43.
Belt 5 passes through among rectangular tube 3 and connects angle grinder 2 and belt pulley 7.Pin 9 is worn in the shaft connection of belt pulley 7,
It wears pin 9 to stretch out from 4 side of mounting base, angle grinding 6 is installed to wear on pin 9 and be ground nut 10 by angle and fix.
